Abstract:
A process for treating a feedstock comprising tantalum- and/or niobium-containing compounds is provided. The process includes contacting the feedstock with a gaseous fluorinating agent, thereby to fluorinate tantalum and/or niobium present in the feedstock compounds. The resultant fluorinated tantalum and/or niobium compounds are recovered.
